This invention has reference to new'and useful improvements. in d1e-structures and to such as are useful in wire 'fence' machines The type of wire fence machinesand die f. Structures towhich the present invention appertains, is bestillustrated inthe patent to my brother, J. W. Sommer, deceased, No.

, 1,078,702, dated. NovemberlS, 1913, and to the die-structure best seen on Sheets Sand 9 I I I r discovered that, if while applyingfthestaple ties the die sections are caused to kink orin- ,ofthe drawings of saidpatent. r ,1 Ithas been a commonpractice, so far as I am aware, and-1t was common practice at the date of the foregoing patent to crimp the longitudinal strand or line wires at the intersections of the strand and stay wires it and atfor nearthe point of applicationof the staple tie wires; but for a longtime difficulties' have been experienced in manufactured wire fencing to stretch the same taut, while at the same time have it remain erect without flexing or bowing vertically, due to various, reasons, to-Wit s0me strands or line wires being longer than others, to the roll straightener on the fence machine doing other than taking most of the short kinks 5 and bends out the stay wires before the stay wire or wires enterthe machine; f

I have discovered, after a long practice in the actual manufacture of what we choose 1 to call straight or stiff stay 'fencing'and the use of same, that the flexingor bowing of the fence vertically, due tothe reasons. stated and many others which might be ,enumer-' ated, is avoided by straightening the stay :7 wires in the machine. by and with the use .10 of improved die-structures when applying thesta'ple ties to the strand and stay wires. This accomplished by providing the receiving andlmovable die members with com- V plementary or coacting faces which crimp orimpress indentations in thestay wires, at points adjacent toand on opposite sidesv of the line wires and] applied staple tie wires,

which takes up any slack or irregularities in 5 theportions of the stay wires between, the

respective sets of die members, and thereby gives a better and moreerect supporting,

effect of the several stay wires and. a much better. appearance to the :fence fabric after it is stretchedup; Furthermore, since it is a common practice, When applying the staple tie wires to the intersections of the strand and stay wires to apply the same by the movement of die sections from one side only of the strand. and stay wires, there is a bowing effec bowing e t to the stays which results in ffect to the fabric thruout the, width ofthe fabric and thereby the length of the stays, an

dent the.

d to counteract such actioriI have {stay wires, as above pointed' out,

that the stay wires are therebystraightened,

or in' 0th ed by su er words,-.the bowing is counteractch'k nk ng and indenting and the staysf'caused to assume an erector upstandion and results in the fabric assuming an unbowed and erect position when stretched. v e I,

Inasmuch as the nvention herein 13 directed to the die-structure and particularly to the complementary or coacting faces of the die sections by means of which the stay wvires are straightened during and at the time the staple wires are applied to the intersections ofthe strand andsta'y wires, and inasmuch as the; arrangement and operation of these dies and thestaple forming and driving means are" all disclosed in Patliance' is placed for an understanding of these features, no stress will be laid on :the same here and no effort will be made tov describe other than those features of structure which bear, directly" on the straightening means for'the-staywires.

' The stationary and receiving dieme'mber designated 1; and the coacting-and mov able die memberis designated 2. It is understood that there is one set of these dies adaptedfor'coaction with and at the junc-- 25,

tion'of each stay wire with a strand wire, with'th-e exception of theniarginal or selvage wires, at which point theends of thestay wiresareusuallywrapped or coiled about the marginal or selvage wires and in this type of structurethe're is usually employed a plunger 3 or some suitable means, preferablyfinovable in vthe die section 2 to force and clinch the staple tie about the intersection of the stayand strand wires Theacting face ofthe memberl is formed or provided'with the transverse wire grooves or slots 4 and 5; the former to receive and provide a seat for the body of the stay, wire A and the latter to receive and provide a '7 y r v end of the wire'grooves or slots 4 are beveled,

V parallel w th said groove orslot, are What seat for thfebo'dy of the strand wire B. The

as at 6,to' enable the stays to slip easily into and out of such grooves or slots. Disposed on opposite sides of the wircgroove or slot 5 and extending for a short distance and is called 'seini circular die seats 7 to receive the ends of the staple ties and direct the same about the wires 'to be secured, when the such grooves or slots designated 8 is best plunger 01' punch'act-s 'on'the arcuateend of the said staple tie, tlie latter forconvenience designated C. r

i The movabledie section '2 is providedin its acting face withavir'c grooves orc slots fo'r'ming'seats for the wires A and B, one of seen in Fig. 2,'and the ends ofsuch slots are beveled as "at 9 'ada ted tofuiiction as do the beveled ends G'of the groove or slot 4:. While I have not shown the means of adjusting the diesections l and 2 in their relation to each other, as in the patent referred to, it isto, be understood that such a pro- 7 .vision would be made to take up any wear .6

duejto use and'alsofor the purpose of ad justing the diesto the work in the machine that proper straightening of the stay Wires 'Inay be accomplished. r

The improvement which I have made in the die structure, and which is best seen in Fig. 2, consists in providing in the acting U face of the die section 1 and preferably in I the groove orslot 4: thereof,.the outwardly presentechor what may be termed the ball faces or rounded projectionslO, one on either side. of and next adjacent the 'die'seats 7,

which said ball faces or rounded projec- ;-tions, toward the outer ends of the grooves or slots 4, recede into such groove or slot tby the concave face 11 terminated at the bev eled ends (3. In contradistinction to this, the acting face of the die section2 is provided, preferably in the grooveor slot 8,

- with concave depressions 12, which normally act opposite and are-complementary to the ball faces 'or rounded projections 10 on the section 1; These faces terminate at their outer portions in bearing points .13 and at their inner portions in bearing points 14.

As will be observed from an examination of Fig. 2, when WiresA'and Bare threaded into the machine and thestaple wire -Q is placed ready for cli'iiching'about the inter- 7 section of wires A and B, the die section 2 moves toward and into coacting position with the'die section 1, while at the same time or in timed relation therewith the plunger" 5 or punch 3 is inovedjforward, engagingythe arcuate endof the staple and causes its ends to'be'directed into the die seats 7'ai'id as'a result directed about the stay wire, as shown.

The'action of stapling'is from one side and toward'the stay wire and to effectively staple tie the wi-res the stay is kinked at the intersection with the strand,fas at D- This ordinarily has a tendency to bow or flex thefabric in the direction'o-f application of the tie wires and it is at or about this moment in the operation, that the complementary or coa'cting straightening means on the die sec tions act'to straighten thestay bykinki'ng or indenting-the stay'at points adjacent to and on opposite sides of the point of application.

ofthe staple ties and revers'ely' to the kink OllJQDCl'D in'the stay wire. These kinks or Tlie'die sections 1 and2 act in tlie'following manner- 21s the'section 2 moves to engaging position, the points of bearing of the acting face ofthe die sections are at 'pointsflO, 13

andM with the .ball faces or rounded pro jectio'ns indenting the stay at E and partially forcing the same betweenthe points '13 and indentations in thestay are" designated 'Eif 14: into the'concave depressions 12; The concave faces'll in thesection 1 will allow a slight depressing of the staytherein', as 'occasion may require,jand as the stays are released from the dies whatever'spring there is l in the stays permits oftheir normal straight posit ionsand with a better and more effective supporting action than where the stays are bowed or flexed.

I am aware, as I have pointed out. that kinking strand wires in fence fabric is old, but Iam not aware, during many years of manufacturing wire fence that any one has ever kinked or indented stay wires for the purpose of straightening the same, especially in straight or stiff stay fencing where staple ties are employed to connect the intersections of the strand and stay wires, wherein the stays become bowed or flexed and as a re sult the fabric will not stretch straight, will not remain upright and gives a'bador un-, sightly appearance; While I have elected-to straighten the stay wires in the diestructure, as being the most convenient and an eco nomical way of accomplishing such straightening it should be obvious that once-such result is accomplished modified practices may be employed and yet come within the'spirit and scope of my invention and I, therefore,

do not want to be limited other than is extially simultaneously straightening the stay stapling operation.
